This custom two-story ADU in Denver was designed and built in partnership with the Denver Housing Authority as part of the West Denver Renaissance Collaborative. Built above a garage with exterior stair access, the project delivers durable, high-performance housing while demonstrating how thoughtful ADU design can support neighborhood density, long-term livability, and citywide housing goals.

This compact Denver ADU was constructed by Prenvalley Builders as an efficient, small-footprint backyard residence. Built on a helical pier foundation to reduce site impact and control costs, the project required thoughtful sequencing, precision framing, and careful coordination to maximize usable space. The result is a durable, well-built accessory dwelling unit designed to perform efficiently within a tight urban lot.

A thoughtfully designed detached ADU built to provide comfortable, independent living within a compact footprint. This Denver backyard ADU showcases Prenvalley Builders’ ability to deliver efficient planning, durable construction, and a fully functional home that supports everyday living while fitting seamlessly into the existing property.
